Add new baseline /organizations endpoint tests

[jhodapp]

Description

This PR seeks to fill out blackbox tests of all the major operations one can do with our /organizations endpoint.

GitHub Issue: None

Changes

• Moves the logging initialization functionality into its own module/struct called logging::Logger - this is to make it possible to use the logger in these (and other) tests
• Creates a test HTTP client/server struct and impl to reuse for blackbox testing endpoints
• Adds a test ensuring all organizations are returned by a GET with no ID specified
• Adds a test ensuring a specific organization instance can be deleted by specifying its ID with DELETE
• Adds a test ensuring that it's possible to create a new organization instance using POST
• Adds a test ensuring a specific organization instance can be updated by specifying its ID with PUT

Testing Strategy

1. Run cargo test at the root of the source tree and observe these 4 new tests pass

Going back to draft PR status because I want to consolidate the repetitious Reqwest client code into a reusable structure used by each test.

Tests look great! Thank you for adding these. I just had one question so far.
